Heat and Temperature - Essay Example

Although, we experience heat in our everyday life, we tend not to pay attention to the kind of heat we are subjected to, its relation to temperature and matter, and other interesting information about it. As a result, we are left in a dilemma if something happens in our…

Whether the matter is in the form of solid, liquid or gas, it consists of molecules. These molecules are in constant movement bombarding each other like billiard balls. Such characteristic of motion is responsible for the production of heat. However, the amount of heat produce depends on the speed of collision produced by the molecules. The faster the motions of the particles are the higher the thermal energy is enough to change the state of the matter from solid to liquid or to gas. With this, it is inevitable not to relate heat with the kinetic theory of matter.
Heat is defined as the transfer of energy from an object with higher temperature to an object with lower temperature (Freeman, 2005). For instance, if you touch a hot iron, you feel the heat as the thermal energy enters your hand because the iron is warmer than your hand. Consequently, if you touch a cold drink, the energy passes out of your hands and into the cold drink. The heat which passes from the hot iron to a colder hand originates in the internal energy of the hot object. The internal energy is the sum of the kinetic energy of the molecules called the molecular energy. The kinetic energy is called the thermal energy. Both kinetic and potential energies of the molecules provide the ultimate source of heat which is only appreciated when there is a difference in the temperature of objects coming in contact together until equilibrium is reached. With this, it is important to note that when one is exposed outside the cold winter, there is a need to wear a coat to slow down the flow of the heat from the body.
Temperature is the state of coldness and hotness of an object measured with a device called thermometer. The expansion and contraction of the mercury within the thermometer is compared in a scale to measure how much thermal energy is present in certain molecules of an object.

Heat is a form of energy which created by the motion of atom and molecules. Atoms and molecules are engaged in random motion inside all matters. In solids these motions are small and hence solids have a finite shape. On the other hand in liquids and gases these atomic and molecular motions are large and hence it is difficult to assume particular shape to liquids and gases.

Heat transfer occurs from a substance or objects that is warm to a substance or object that is cooler. Scientists measure heat energy using the ordinary unit of energy, the Joule (Sullivan & Edmondson 2008). Nasser (2009) adds that the movement of heat energy happens from a system to the other.

(Liboff, 1990) The addition of energy especially heat energy triggers particles to move faster while the removal of heat energy slows the particles down. Hence, if the state of heat energy of a system is known then the speed of its particles can be ascertained to a reasonable extent.

In the latter literature presented therein, we would fundamentally look into various methods and definitions employed to exactly what heat and temperature are with regards to the kinetic theory of matter and how they particularly influence this law.

Energy is measured on the earth in the form of both heat and temperature. Temperature is the average kinetic energy of the molecules and atoms of a substance. According to (Gavin 104-7) “The concept of temperature is as fundamental a physical concept as the three fundamental quantities of mechanics—mass, length, and time.

According to the theory, matter is composed of a number of small particles that are called atoms or molecules and these atoms or molecules are always in movement and their movement is multidirectional. Study is heat is related to kinetic theory of matter as heat is a process in which, thermal energy shifts from one object to the other and the movement of molecules get faster with shifting of thermal energy.

This paper also explains the transitional state of matter from solids to liquid, then to gas and the energy involved to break the bond. The result of this work finally gives an insight of how heat transfer relies on temperature variation to move from a source or a region of high to lower concentration.

As stated by the theory, matter is made up of tiny particles called molecules or atoms that move in motion. Solids have particles that are compactly bounded to each other that can cause vibration movement rather than moving from one location to another. Kinetic theory can also be used to describe the many physical states of matter.

Later, Albert Einstein described the motion through what came to be referred to as the molecular theory of matter, also referred to as kinetic theory of matter. This postulates that all matter would be constituted of tiny particles referred to as molecules which constantly move and bounce off each other just like the billiard balls.

Mammals and bird are the only known animals to maintain their normal temperatures even with fluctuations of temperature in their surroundings. The first way of regulating external body temperature is through conduction, where the body conducts heat to the environment (IHW, 2006).
